This usually is a result of pdf2fax or ps2fax (Ghostscript) putting them
there. Probably indicating that the shade or color that contains the little
black dots is really not white (#000000), and so Ghostscript is attempting to
simulate the shade with those dots.
So, fix the image you're converting or bypass ps2fax.
